Use the links above or do an advanced search in ppubs for:
(D8/82.ccls. or D8/83.ccls. or D8/84.ccls. or D8/85.ccls. or D8/86.ccls. or D8/87.ccls.)
This will show what classes derive from the input. Ex: entering 43/42.24 shows the derived classes and the search that can be used to find patents or patent applications in those subclasses.
